I'm trying to add a second 16 GB DDR5 stick to an ASUS B850M-A motherboard. The existing stick and the new one are both ADATA XPG Lancer Blade. I've opened the latch, but the new stick won't click in and I'm worried about damaging the slot. What should I check?
How do I get my second RAM stick into the slot?

First, shut down the PC, switch off the power supply and unplug it. Check the motherboard manual for the recommended slot when using two sticks, then open the movable latch or latches on that slot. Some slots only have a latch at one end.
Line up the off-center notch on the stick with the ridge in the slot. Don't use the logo as your orientation guide. Set the stick straight into the slot and press down firmly and evenly on both ends until it's seated and the latch closes. It can take more pressure than you might expect, but stop if it's visibly crooked or something is obstructing it. Don't force the latch closed by hand over an unseated stick.

If it still won't go in, take it back out and look closely at the slot and the stick's contacts for debris or damage. Check that the notch is actually lined up with the ridge, not just that the two sticks face the same way. A clear photo of the slot and stick could help someone spot what's off.

Once it's seated, reconnect power and check whether the BIOS or operating system reports the full 32 GB. Two separately purchased sticks, even of the same model, aren't guaranteed to run together at their advertised profile speed. If you get crashes or freezing, try the default memory settings first. A matched kit is another option if stability remains a problem.

A seated stick should sit level, with the contacts mostly hidden in the slot. Compare its position with the existing stick.
